I have a degree in Mech. Eng and a Masters in IT. I am far from geeky - quite the opposite - and I have to say so are the (female) mates I've met through the industry - we are in fact all incredibly girly, we just happen to work in a male dominated industry.
I have found however, that the women I have met in the industry tend to go down the business route (when I say that I mean becoming business/requirements analysts in an IT industry, or project managers) Only one has stayed techy (dba) and I would only now describe myself as semi-techy (I test software - once upon a time I was a developer, and also a dev manager for a bit (which I hated - I'm a worker bee, not queen bee) but I wasnt good enough at it in my opinion and ended up in testing - still lucrative if you understand the software lifecycle and get around a database). I ditched engineering after my degree as I found myself designing high pressure steam pipes in my year out and it bored me stupid - put me right off LOL)
I have never, ever had an issue with being a female in a male dominated industry. I have worked for very very large international companies, (10k+ employees worldwide) and currently work for a very very small one (20 employees) and all have employed me on ability I'd like to think, not novelty factor or any other random reason.
I'm all for encouraging both sexes into technical roles. It never once occurred to me during my teens that I 'couldnt' go into engineering for any reason. It just never occurred to me that I could either. Because it was never suggested. I only took it to be a bit 'different'. It wasnt until I was actually doing the course that I realised I was better at it ('it' covering a wide range of subjects) than the other folk, regardless of gender. I enjoyed a lot of it too (mostly the beer, but I was freakishly good at mechanics of solids - what the hell is that?!!)
Possibly if someone had suggested it to me I'd have thought about it earlier (during A-levels) whereas for me it was just a random - ok right I've changed my mind about that textiles degree - what now? moment.
I think that it should have been made more appealling in sixth form. To everyone. I was clearly good at maths and science, (also art) but no-one ever suggested engineering to me - just architecture (gah - no!!). Why on earth not? I do think though, and I am being very general, that female brains are just not wired like mens. I do. sorry. And this means that engineering/IT type subjects are simply just not appealling (again, generalising big time). Its nothing to do with whether they are 'as good at it' or not - its some sort of basic make-up.
That doesnt mean I dont think we need to advertise the opportunities more. We do. Because there are always exceptions. Possibly a heap of them, and they arent being given the information they should be.
